I actually just got off the phone with my buddy that I mentioned above. He told me that he never not once ever in his life got 10 mpg's with his. He is far from a speed demon either. I want to say his was an '03.
I averaged around 8 mpg when I pulled a trailer at my job. I was responsible for filling out a fuel log and filling up all the equipment on a daily basis for 2 years. So I am pretty confident in my #'s. I certainly had a heavy right foot at work and was known to leave the truck running during jobs with the AC on so factor that in.
Personally I doubt there is much difference in 3.73 vs 4.10 as far as gas mileage is concerned. To be honest I don't know what gears were in the work truck but do know for sure my buddy and uncle both had 4.10's.
